/*
Every C++ program contains one or more functions, one of which must be named
main. The operating system runs a C++ program by calling main. Here is a simple
version of main that does nothing but return a value to the operating system:
*/

int main()
{
	return 0;
}

/*
A function definition has four elements: a return type, a function name, a (possibly
empty) parameter list enclosed in parentheses, and a function body. Although main is
special in some ways, we define main the same way we define any other function.
